Do you know the History of Digital Forensics?

Before the 1980s, crimes involving computers and digital devices were dealt with using existing laws. So, the field of digital forensics is relatively new. While its history may be short, it is quite complex.

As the years went by, the range of digital crimes being committed increased, but it was not until the 1980s that federal laws began to include computer offences. Canada was actually the first country to pass legislation in 1983, followed by the US Federal Computer Fraud and Abuse Act in 1986.

The fact that computer and digital crimes grew so much during the 1980s and the 1990s caused law enforcement agencies to start making specilised groups to deal with the technical aspects of the investigation. For example, the Computer Analysis and Response Team that the FBI formed in 1984.

Throughout the 1990s there was a high demand for these new investigative resources, this lead to the creation of regional and even local level groups to help handle the load. But, it was not until 1992 that the term “computer forensics” was actually used in academic literature.

Since the year 2000, a lot of people and agencies have written and published guidelines for digital forensics. A European lead international treaty, the Convention on Cyber crime, came into force in 2004 with the aim of reconciling national computer crime laws, investigative techniques and international co-operation.

Since the late 1990s digital devices have become available everywhere, basically everyone has a phone or some kind of digital device. Devices have advanced way beyond simply communicating, they are great forms of information, even for crime not usually associated with digital forensics. However, digital analysis of phones has lagged behind traditional computer media, mostly because of problems over the ownership of the devices.

The complex field of digital forensics will always have unresolved issues. Many issues will include; increasing size of digital media, the wide availability of encryption to basically everyone, the variety of operating systems, increasing number of people owning multiple devices and lets not forget the legal limitations on investigators.

How does a Criminal hack your Cellphone?


A lot of people would be really surprised if they knew how easily hackers gain access to cellphones to steal personal and private data or information.

These days cyber criminals have software and systems that can hack your mobile phone with just your number, where they listen to your private calls, read your messages and emails, access your online banking and anything else you store on your phone.

A hacked phone is a concern to most people, but it is even more of a concern to massive enterprises and businesses across the globe. Cellular phones are used daily by businesses and often sensitive information is shared over calls and through messages, meaning a hacked phone can lead to loss of financial data and important customer information!

What is even scarier is the fact that tutorials on how to hack cellphones can be found on the internet for just about anyone to access. This is why it is so vital for everyone to set up security to protect their mobile phone and communications.

Did you know that every year billions of phones are hacked because they are unprotected?

Securing your phone and communications from hackers requires multiple steps including creating secure, unique passwords, avoiding public Wi-Fi connections, and diligence in checking links in emails and messages to ensure authenticity before clicking on them, and encrypting calls and messages.

Smartphone Safety for Children

It’s 2018, we’re more connected than we were a few years ago and we’re continuing to grow as time goes by.

These days, teenagers and even small children are getting caught up in all the new technology that is being introduced. The ability to communicate with friends with the push of a button is a sought after thing, and having a smartphone is a privilege that all teenagers assume they should have. However smartphones can bring a few dangers with them.

It’s about time you sit down with your children and have a chat with them about smartphone safety…

You will never be able to remove them completely from the world of technology, so make sure to sit down and have an educational conversation instead of arguing with them.

Who are they talking to? Are they chatting to their friends or someone they met online? Let them know that people are usually not who they seem to be online and they should apply “stranger danger” online as well as in the street.

What kind of content are they looking at? Are the apps, games, videos, etc. they’re looking at appropriate for their age? Remember to be aware of any cyberbullying is taking place.

Are they texting and driving? Texting and driving is beyond dangerous, especially for young teens who have just started driving and have little experience. There are apps you have use to control this, but there should be strict rules in place too.

The most important skills you need for a career in Digital Forensics

Tech meets criminal justice in the field of digital forensics--a branch of forensic science dealing with recovering and analyzing information from data storage devices (including computers, phones, networks, and more). Digital forensics examiners help track down hackers, recover stolen data, follow computer attacks back to their source, and aid in other types of investigations involving computers.

Image result for digital forensics

Want to know what it takes to become a digital forensics examiner? Here are some key skills needed for the career…

Analytical talent: It stands to reason that anyone in an investigative role needs to have the analytical skills required to piece together information and solve the case. Cyber security expert, Ondrej Krehel says: “High speed of analytical thinking, and precise observation skills, which are often gained and tested at high tech military and intelligence cyber units are also important skills to have." The ability to find patterns and make correlations is crucial in the investigation process!

Computer science/tech skills: Since digital forensics is such a technical field, it helps to come from a background studying or working with computer science. An important quality of any great digital forensics investigator is a deep understanding of how technology really works. If you have experience with computer systems, programming, or other related fields, this will help you transition into digital forensics since you will already have a general knowledge of how technology and networks work, how digital systems interact with each other, and what is possible from a compromise perspective.

Understanding of cybersecurity: The field of digital forensics is all about solving cybercrimes--and who has a better knowledge of those than cybersecurity professionals? It's impossible to guard against data breaches without knowing the techniques being used to target systems, and this same knowledge that helps to prevent crimes also is useful in solving them. Many of the most talented forensics examiners will have had experience working on a cybersecurity team.

Organisation: You can have a messy desk and be a great digital forensics examiner--but mental organisation is a must, as is organised record-keeping. Being extremely organised and thorough is a must! Documentation of your findings is necessary as it is often required to present them to others such as attorneys and judges.

Communication skills: In relation to the above point, digital forensics doesn't exist in a vacuum. The team you work with and people you work for need to know what's going on, meaning that you need to communicate it to them. According to Ondrej Krehel, "Having both strong writing and speaking skills is extremely important to effectively communicate your findings to other team members and your clients."

Desire to learn: Cybercrime is constantly evolving, so it's a must to keep your knowledge up-to-date and always seek out ways to be better at your job. To be a digital forensics examiner, you must have great pride to be one of the best in what you do. Self-critique skills for constant improvement of your work is a very desired trait!

As for higher education, degrees are helpful in breaking into the digital forensics field, but what really establishes someone's credentials is the product of their work and the ability to conduct digital forensics in very detail-oriented manner!
At TCG Digital Forensics, we do all forms of Digital Forensics such as Cyber Forensics (Penetration Testing / Hacking Recovery / Cyber Investigations), Cellular Phone Analysis, Hard Drive Analysis, Device Acquisitions and Due Diligence Investigations.

We can recover Computer Evidence quickly and easily!

People use their computers for almost everything; many of these things can be used against you. Hiding money, illegal activities, inappropriate emails and just about anything you can think of.

Often, if you are trying to hide something, you’ll make an effort to completely clean out your computer by deleting “everything” and reformatting. The problem is, when you contact IT support and you are told that all is lost, they probably have no idea what a digital forensic investigator can do!

Image result for digital forensics

The harsh truth is that the evidence is still there, waiting to be found, you just can’t see it. The only question is, do you want it recovered or not.

Many businesses that have a disgruntled employee, or feel that an employee is involved in unacceptable activities at work, may want to acquire some digital evidence, they can use a digital forensic investigator to recover all the evidence that they need.

At the TCG Digital Forensics Division, we are pleased to provide all the evidence that you need off of a computer, cellular device, laptop or tablet. The obvious advantage that we have is that we recover digital evidence that few others could and keep all affairs private!

Need something recovered? Don’t hesitate to give us a call on 079 691 0138 or email craig@tcgforensics.co.za
